Adrien Grand commented on LUCENE-5352: -------------------------------------- I ran tests as well and got similar results. It may be possible to optimize this reader (maybe reversing the bytes in the call to readLong takes substantial time on little-endian computers (just guessing)?) but taking a step back, I'm wondering that maybe this aligned format should be deprecated. As [~toke] noted last year, the in-memory impl is not faster than Packed64 on all CPUs, so if the speed-up is not clear for disk-based structures either, I think we should just deprecate it? > PackedInts.fastestFormatAndBits returns slower format for Direct > ---------------------------------------------------------------- > > Key: LUCENE-5352 > URL: https://issues.apache.org/jira/browse/LUCENE-5352 > Project: Lucene - Core > Issue Type: Bug > Reporter: Robert Muir > > from some simple testing, DirectPacked64SingleBlockReader seems slower than > DirectPackedReader (at least in a few cases i tested, more testing needed, > but look at the code). > this is unintuitive, because by passing e.g. FASTER you are making it slower. -- This message was sent by Atlassian JIRA (v6.1#6144) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
